Frequently Asked Questions

What media can I use with this insert tray?

The Super Sprouter 50-Cell Insert Tray is compatible with coconut coir plugs, Grodan stonewool (rock wool) starter plugs, regular seed-starting soil, and all common soilless propagation mixes for both seeds and cuttings.

How does this insert compare to standard competing insert trays?

The Super Sprouter insert is built heavier-duty than most competing products - thicker walls and a more robust build mean it resists cracking and deformation better, lasting longer through repeated use and cleaning cycles.

Does each cell have a drainage hole?

Yes - every cell has individual drainage holes to allow excess water to drain freely, preventing waterlogged media and keeping the root zone in optimal condition for germination and rooting.

What trays does this insert fit?

The insert fits any standard 10in x 20in (1020) propagation tray, including all Super Sprouter standard and Quad Thick trays, and most other brand standard nursery flats.
